Abstract

A digital-to-analog converter includes a first channel configured to output a first ramp voltage through an output node, and a first bias circuit configured to apply a bias voltage to the first channel. The first channel comprises a plurality of current cells connected to the first bias circuit, a plurality of selection circuits and a plurality of switches, and a first resistor connected to the output node. Each of the plurality of selection circuits of the first channel comprises a first selection circuit configured to connect a current of one of the plurality of current cells to the first resistor in accordance with a first digital input signal, and a second selection circuit configured to connect the current of the current cell to one of the plurality of switches corresponding to the current cell in accordance with a second digital input signal complementary to the first digital input signal.
